IMPROVEMENT iN BEER-FAUCETS. y

Specification forming part of Letters Patent No. 129,938, dated July 30,` 1872.

laucets, but the manner of constructing here rdescribed may be employed in making faucets for other purposes besides drawing olf beer.

` Figure 1 of accompanying drawing is a longitudinal section of my faucet. Fig. 2 is an end view, showing strainer.

Referring to the drawing, A is a bush or socket-piece, which tapers slightly from the shoulder ato the end. From the shoulder a to the end a fine-threaded screw is cut. This piece accommodates the valve B, which controls the iow of the liquid, and is screwed into the head of the barrel. The valve B rests against a rubber seat, C, being held, when closed, against this seat by the spiral spring b wound round the stem ofthe valve. D is a plug having several holes through it to permit the liquid tp pass through. This plug is screwed into the end of the bush-piece, which projects into the barrel.A At the outer end of the bush-piece, which projects outside of the barrel, there is an internal screw cut, and into this the conduit-stem E of the faucet is screwed. F is the operating-rod, which terminates, after passing beyond the conduitstem, in a little wheel, G. This rod F has a double-threaded screw at f, which screws into a corresponding thread cut in the interior of the conduit-stem. H is a packing-box of usual form, supplied, where the rod F passes out of the conduit-stem, to prevent leakage. I is the exit-passage for the liquid.

The operation is as follows: The bushpiece is inserted inthe barrel-head, and may remain there until the barrel is worn out. The stem' part of the faucet is applied when the liquid is to be drawn off, the flow being regulated by screwing the rod F against the valve B.

Instead of the double-threaded screw being supplied on the rod F, this rod may be pushed forward and drawn back by other suitable mechanism not necessary to describe.

I know of the beer-faucet invented bynAl- Vfred Hallowell in 1865, covered by patent No.

48,273. This faucet, like mine, has a bushpiece with valve inserted; but the valve in Hallowells device does not serve to regulate the liow of the liquid when the faucet is inserted, but is only serviceable when the faucet is withdrawn. Hallowells valve is a plug stopping the hole for the faucet. My valve is part of the faucet itself.

I do not claim the bush-piece A broadly, for bush-pieces have been used before, nor do I claim the means of operating the valve B by the rod F.

I claim- The peculiar construction and arrau gement of the bush-piece A, forming also a chamber and seat for the valve B, in combination with the valve B, as and for the purposes as herein shown and described.
